For adults 19 years of age and older, the deltoid muscle in the upper arm is the preferred site, although the vastus lateralis muscle in the anterolateral thigh may be used if the deltoid site cannot be used.
People also ask, is flu shot subcutaneous or intramuscular?
Typically, the regular seasonal flu shot is given intramuscularly (IM), meaning it's injected into the muscle. However, a subcutaneous (SQ) version of the shot has become available for the 2011 to 2012 flu season. It's given with a smaller needle and is injected into the skin.
What size needle is used for flu shots?
Influenza vaccines are not highly viscous, so a fine-gauge (22- to 25-gauge) needle can be used. Use a ?- to 1-inch needle for men and women who weigh less than 130 pounds (less than 60 kg). Insert the needle at a 90-degree angle and stretch the skin flat between thumb and forefinger.
Is the flu shot a live vaccine?
The nasal spray flu vaccine does contain live viruses. However, the viruses are attenuated (weakened), and therefore cannot cause flu illness. The weakened viruses are cold-adapted, which means they are designed to only cause infection at the cooler temperatures found within the nose.
